LATERAL-MOTION JOURNAL-BOX.

Specification of Letters Patent. t t 1917,

Application filed April 3, 1916. Serial No. 88,556.

To all whom it may concern:

Be it known that I, FRANKLIN L. BARBER, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented. certain new and useful Improvements in Lateral-Motion J ournal-Boxes, of which the following 1s a specification.

My invention relates in general to lateral motion journal boxes for car trucks of the type covered by United States Patent No. 1,118,621, granted to me on November 24, 1914, and more particularly to prov1d1ng a journal box which may be readlly converted from the lateral motion type to the r1g1d M. C. B. type.

Each journal box under the recommendation of the M. C. B. Association is provided on its inner side surfaces with opposed vertical stops of standard dimensions upon which the journal bearing and wed e fit, and which, through engagement wit lugs on the bearing, serve to prevent movement of the journal box inwardly with respect to the axle journal.

The primary object of my invention 1s to provide a journal box of the lateral motlon type in which the parts will be so arranged and proportioned that the inner surfaces of the sides of the box may be provided with opposed vertical stops of the M. G. B. standard dimension, and which will guide and properly position the rollers and the journal bearing in the upper surface of which the roller seats are formed, and which will permit, in case of emergency, the substitution of standard M. C. B. journal bearing and wedge for the rollers and special journal bearing with roller seats, thereby renderlng the 'ournal box readily convertible from one of t elateral motion type to one of the usual rigid M. C. B. type. j

A further object of my invention is to provide a journal box of the lateral motion type in which a standard journal bearln'g and wedge may be substituted for the rollers and special journal bearing having roller seats therein.

A still further object of my invention is to provide a journal box of the lateral motion type which will be simple in construction, convenient in use, and efficient in oporation.

My invention will be more fully disclosed hereinafter with reference to the accompanying drawings, "in which the same is illustrated as embodied in a convenient and practical form, and in Which Figure 1 is a side elevational view, port1ons belng broken away, showing the journal box provided with" standard journal Fig. 3 1s a vertical section on the line 33 of Fig. 1;

Fig. 4 is a vertical section on the line -H of Fig. 2;

Fig. 5 is a plan view, parts being. broken away, of the rollers in their supporting cage removed from the journal box; and

Fig. 6 is an elevational view of the roller cage.

Similar reference characters are used to designate similar parts in the several figures of the drawings.

Reference letter A designates the journal box having the usual bearing B on its top for en agement with the arch bar of the truck frame, ribs B and B serving to engage the opposite edges of the arch bar. C and C? indicate vertical pairs of ribs projecting outwardly from the opposite side walls of the journal box for engaging the usual bolts connecting the arch bar and tie bar of the truck side frames. A designates the usual opening through the outer wall of the journal box to permit access to the in terior thereof, while a designates a bracket for' supporting the journal box lid. D indicates the usual space for a dust guard to closely surround the axle E adjacent the journal 6 thereof.

F designates the journal hearing, or brass, which is curved transversely to conform to the curvature of the axle journal e, and is of a length longitudinally to fit between the shoulder e and the collar 6 the latter being at the end of the axle journal. G designates the journal wedge which overlies and is supported upon the journal bearin F. The inner end of the journal wedge engages a rib f projecting upwardly around the inner end of the ournal bearing, while the outer end of the journal wedge is provided with a projecting portion adapted to enage lugs 9 formed on the opposite sides of "t e undersurface of the journal box top adjacent the opening A Formed integrally with the journal box on the inner surfaces of the side walls thereof are vertical stops H H which pro ect upwardly from a plane slightly below the top of the axle journal to the undersurface' laterally projecting lugs 7, on the sides of.

the journal bearing F, to limit the outward movement ofthe journal box relatively to the axle. The inward movement of the journal box relatively to the axle is prevented through the engagement of the wedge with the lugs 9. When the parts above described are assembled, as shown in Figs. 1 and 3, the journal box and axle journal are therefore prevented from relative lateral movement.

In order that the journal box may have a lateral movement relatively to the axle journal, so as to relieve the strain and wear upon the wheel flanges by allowing the car truck to move slightly laterally with respect to the axles, I replace the usual M. C. B.

journal bearing F and wedge G by a journal bearing K carrying a plurality of concave roller seats L on its upper surface, such roller seats being preferably formed integrally with the journal bearing. Other concave roller seats M are formed in the undersurface of the top wall of the journal box A in vertical registry with the roller seats on the upper surface of the journal bearing K. A plurality of rollers N are interposed between the vertically alining' concave seats formed in the upper surface of the journal bearing and undersurface of the top wall of the journal box, and serve to support the journal box, and through it the car truck and car upon the-axle journal through the medium of the journal bearing. In order that the series of rollers N may be conveniently inserted and removed, a cage 0 is provided, in the opposite side portions of which are formed bearings 0 for the trunnions n on the opposite ends of the rollers N. The cage 0 is constructed of two duplicate parts having overlapped end portions 0 and o -through which pass suitable fastening devices, such, for instance, as screws p. The hearings in the cage for the roller trunnions are spaced apart to correspond with the alined concave roller seats in the undersurface of the top wall of the naaaao? journal box and upper surface of the journal bearing. The rollers with the surrounding cage are of a size to pass inwardly and outwardly through the upper portion of the usual opening A of the journal box, and in order to facilitate the insertion of the rollers the cage is made symmetrical so that either end thereof may be inserted first, and so that either side thereof may be presented upwardly. In order to facilitate the Withdrawal of the cage containing the roller bearings, holes 0 are formed in the ends of the cage which may be engaged by a hook of the construction ordinarily used for removing waste from journal boxes.

he journal bearing K and cage 0 are of a width to fit between and to be guided by the stops H and H on the inner surfaces of the side walls of the journal box, when such stops conform to the M. C. B. standard dimensions. The said stops retain the journal bearing and roller cage in alinement intermediate the axle ournal and Endersurface of the top wall of the journal From the foreging description it will be seen that in my improved lateral motion journal box the journal bearing which is provided in its upper surface with the roller seats, and the cage within which the roller bearings are supported, are of a width to fit between the vertical stops of standard M. C. B. dimensions, and consequently should an emergency occur, the cage and journal box ma be removed and replaced by a standard C. B. journal bearing and wedge, such parts at the present time being more universally obtainable than are roller bearings and journal bearings having seats to accommodate the roller bearings. It will therefore be evident that by means of my invention a journal box may be readily converted from one of a lateral motion type to one of a rigid type,

by merely replacing the roller bearings and special journal bearin with a standard journal bearing and we ge.

What I claim is 1. In a journal box the combination of a top wall provided with spaced anti-friction bearing seats the metal in the spaces between said seats being shaped to operatively function with an M. C. B. wedge, a journal bearing havin seats, and anti-friction elements cooperatmg with the seats and adapted to movably support the box on the bearing, substantially as described.

2. In a journal box, the combination of a top wall having a plurality of anti-friction bearing seats, the metal in the intervening spaces being finished to conform to the upper surface of a prescribed standard :wedge, a brass having a flat upper surface pro vided with bearing seats which register with said first-mentioned seats in a normal posi-' tion of the parts, and anti-friction elements held between said seats, substantially as described.

3. In a journal box the combination of a horizontal wall, a bearing brass, bearing rollers and a cage for-retaining the same, said rollers being interposed between and in direct contact with said wall and brass, the vertical depth of said brass and rollers being equal to the vertical depth of a combined brass and wedge of standard dimensions, substantially as described.

4. In a journal box the combination of a to wall provided with a lurality of seats, a caring brass having a at upper surface of substantially the width of the box, said brass also being provided with seats, and

a plurality of rollers, rigidly held in spaced relation and adapted to be located between and in direct contact with said wall and brass, 20

In testimony whereof, I have subscribed 25 my name.
